ABSTRACT

Background: Parents tend to visually assess children to determine their weight status and typically underestimate child body size. A visual tool may aid parents to more accurately assess child weight status and so support strategies to reduce childhood overweight. Body image scales (BIS) are visual images of people ranging from underweight to overweight but none exist for children based on UK criteria. Our aim was to develop sex- and age-specific BIS for children, based on British growth reference (UK90) criteria. Methods: BIS were developed using 3D surface body scans of children, their associated weight status using UK90 criteria from height and weight measurements, and qualitative work with parents and health professionals. Results: Height, weight and 3D body scans were collected (211: 4-5 years; 177: 10-11 years). Overall, 12 qualitative sessions were held with 37 participants. Four BIS (4-5-year-old girls and boys, 10-11-year-old girls and boys) were developed. Conclusions: This study has created the first sex- and age-specific BIS, based on UK90 criteria. The BIS have potential for use in child overweight prevention and management strategies, and in future research. This study also provides a protocol for the development of further BIS appropriate to other age groups and ethnicities.

ABSTRACT

BACKGROUND: There is a plethora of cross-sectional work on maternal perceptions of child weight status showing that mothers typically do not classify their overweight child as being overweight according to commonly used clinical criteria. Awareness of overweight in their child is regarded as an important prerequisite for mothers to initiate appropriate action. The gap in the literature is determining whether, if mothers do classify their overweight child's weight status correctly, this is associated with a positive outcome for the child's body mass index (BMI) at a later stage. OBJECTIVE: To explore longitudinal perceptions of child weight status from mothers of a contemporary population-based birth cohort (Gateshead Millennium Study) and relationships of these perceptions with future child weight gain. METHODS: Data collected in the same cohort at 7, 12 and 15 years of age: mothers' responses to two items concerning their child's body size; child's and mother's BMI; pubertal maturation; demographic information. RESULTS: Mothers' perceptions of whether their child was overweight did not change markedly over time. Child BMI was the only significant predictor of mothers' classification of overweight status, and it was only at the extreme end of the overweight range and in the obese range that mothers reliably described their child as overweight. Even when mothers did appropriately classify their child as overweight at an earlier stage, this was not related to relatively lower child BMI a few years later. CONCLUSIONS: Mothers tend to classify their child as overweight in only more extreme cases. It is an important finding that no beneficial impact was shown on later child BMI in overweight children whose mothers classified their child's weight status as overweight at an earlier stage.

ABSTRACT

This study investigated the accuracy and maintenance of reduction of intra-articular steps achieved with closed reduction and percutaneous K wires and open reduction and a volar locking plate for the treatment of intra-articular distal radius fractures. We performed a retrospective review of 359 patients with an intra-articular fracture of their distal radius. Multivariate linear regression was undertaken to investigate the influence of multiple variables such as age, gender, initial displacement and treatment method on reduction despite differences between groups. A total of 36% of patients treated with K wires and 29% with volar locking plate had a step greater than or equal to 1 mm present on the first post-operative radiograph. A total of 23% treated with K wires and 28% with volar locking plate had a residual step of 1 mm or more on the last available radiograph. There was no difference identified between the two techniques for quality of initial reduction or persisting step on the last available radiographs. Step behaviour and further reduction of step post-operatively was similar for both treatment methods. Initial displacement and increased age influenced initial reduction. Initial fracture displacement shown radiologically was the only variable identified that influenced the persistence of a step on post-operative radiographs. LEVEL OF EVIDENCE: IV.

ABSTRACT

BACKGROUND: Hip and wrist fractures are the most common orthopaedic injuries. Combined hip and distal radius fractures are an important clinical and public health problem, since mobilisation and rehabilitation is challenging and likely to be prolonged in this setting. Few studies have explored the influence of an associated wrist fracture in patients with hip fracture. We present the largest series of patients with concomitant hip and wrist fractures. We perform the first meta-analysis of the literature on patients with concurrent hip and wrist fractures. MATERIAL AND METHODS: In this single-centre retrospective study we compared 88 consecutive patients with simultaneous hip and wrist fractures with 772 consecutive patients who suffered isolated hip fractures. RESULTS: Patients with the combined fracture were of a similar age compared to those with isolated hip fracture. There were a significantly higher proportion of women in the cohort with both hip and wrist fractures (female:male ratio of 9:1 versus 4:1 p < 0.0001). The combination fracture group had a greater length of hospitalisation (18 vs 13 days p < 0.0001). The survivorship of both groups was not significantly different even after adjustment for age and gender. Meta-analysis of the literature showed female preponderance, increased length of stay but no significant difference in survival in patients with concomitant hip and wrist fractures. CONCLUSION: The combination fracture occurs much more commonly in women and patients require a greater length of hospitalisation. The patients who sustained simultaneous hip and wrist fractures experienced no statistically significant difference in survivorship when compared to those who suffer isolated hip fractures. This is not withstanding the presence of two fractures. This difference in mortality did not reach statistical significance. LEVEL OF EVIDENCE: Level III (retrospective comparative study).

ABSTRACT

Volar locking plates are an increasingly popular treatment for distal radius fractures. We reviewed complications observed after volar locking plate fixation in a busy teaching hospital. The purpose of the study was to assess whether complication rates after volar locking plate use in general, routine trauma practice were higher than published literature from expert users. A retrospective review was carried out of patients treated with a volar locking plate between January 2009 and December 2010. The series included 206 procedures in 204 patients (77 males and 127 females) with mean age of 55 years (range 16-94). Surgery was performed by 18 different consultant surgeons and 11 registrars. A total of 22 complications were observed in 20 patients with an overall complication rate of 9.7%. Seven (3.4%) patients developed tendon problems including four (1.9%) tendon ruptures. Four (1.9%) patients required re-operation for metalwork problems; four patients developed complex regional pain syndrome (CRPS). Three fracture reduction problems were noted. A total of 16 further operations were carried out for complications. The overall complication rate was low even when surgery was done by many surgeons, suggesting that this is a safe and reproducible technique. This study provides information which can be used to counsel patients about risks, including those of tendon and metalwork problems. This allows patients to make an informed decision. Surgeons must have specific strategies to avoid these complications and remain vigilant so that these can be identified and managed early.

ABSTRACT

BACKGROUND: 5-HT(2B) receptors are localized within the myenteric nervous system, but their functions on motor/sensory neurons are unclear. To explore the role of these receptors, we further characterized the 5-HT(2B) receptor antagonist RS-127445 and studied its effects on peristalsis and defecation. EXPERIMENTAL APPROACH: Although reported as a selective 5-HT(2B) receptor antagonist, any interactions of RS-127445 with 5-HT(4) receptors are unknown; this was examined using the recombinant receptor and Biomolecular Interaction Detection technology. Mouse isolated colon was mounted in tissue baths for isometric recording of neuronal contractions evoked by electrical field stimulation (EFS), or under an intraluminal pressure gradient to induce peristalsis; the effects of RS-127445 on EFS-induced and on peristaltic contractions were measured. Faecal output of rats in grid-bottom cages was measured over 3 h following i.p. RS-127445 and separately, validation of the effective doses was achieved by determining the free, unbound fraction of RS-127445 in blood and brain. KEY RESULTS: RS-127445 (up to 1 micromol x L(-1)) did not interact with the 5-HT(4) receptor. RS-127445 (0.001-1 micromol x L(-1)) did not affect EFS-induced contractions of the colon, although at 10 micromol x L(-1) the contractions were reduced (to 36 +/- 8% of control, n= 4). RS-127445 (0.1-10 micromol x L(-1)) concentration-dependently reduced peristaltic frequency (n= 4). RS-127445 (1-30 mg x kg(-1)), dose-dependently reduced faecal output, reaching significance at 10 and 30 mg x kg(-1) (n= 6-11). In blood and brain, >98% of RS-127445 was protein-bound. CONCLUSIONS AND IMPLICATIONS: High-protein binding of RS-127445 indicates that relatively high doses are required for efficacy. The results suggest that 5-HT(2B) receptors tonically regulate colonic motility.

ABSTRACT

This study identified variables which influence the outcome of surgical management on 126 ununited scaphoid fractures managed by internal fixation and non-vascular bone grafting. The site of fracture was defined by a new method: the ratio of the length of the proximal fragment to the sum of the lengths of both fragments, calculated using specific views in the plain radiographs. Bone healing occurred in 71% (89) of cases. Only the site of nonunion (p = 1 x 10(-6)) and the delay to surgery (p = 0.001) remained significant on multivariate analysis. The effect of surgical delay on the probability of union increased as the fracture site moved proximally. A prediction model was produced by stepwise logistic regression analysis, enabling the surgeon to predict the success of surgery where the site of the nonunion and delay to surgery is known.

ABSTRACT

Achieving union using conventional grafts has a high chance of failure in patients with recalcitrant non-union (persistent pseudarthrosis) of the scaphoid bone, an avascular proximal fragment and previous failed surgeries because of poor host bed vascularity. Eleven patients with long-standing non-union were treated with vascularized pedicle bone grafting and supplementary corticocancellous grafting. Five had screw fixation and six were fixed with K-wires. The average age of the patients was 28 years, average duration of the non-union was 39 months and mean radiological follow-up was 32 months. There were no significant skeletal complications, although two patients developed neuromata. At review, only six of the 11 non-unions were united. Whilst this is a difficult clinical problem and achieving union is a formidable challenge, we believe that there is a role for such extensive surgery in order to achieve good postoperative function.

ABSTRACT

Iliac crest bone grafts are sometimes preferred to other bone grafts for the treatment of non-unions of fractures of the scaphoid as they are claimed to have better osteogenic potential and biomechanical properties. We retrospectively studied a consecutive cohort of 68 symptomatic established scaphoid non-unions treated by bone grafting. An iliac crest graft was used in 44 cases and a distal radius graft in the other 24. The two treatment groups were comparable in terms of location of the fracture, duration of the non-union and the fixation implants used. Overall union was achieved in 45 of the 68 patients (66%) and the union rate was not influenced by the type of bone graft used. Twenty-nine of the 44 treated with iliac crest bone graft (66%) and 16 of the 24 (67%) treated with distal radial graft united. Donor site pain over the iliac crest was present in nine of the 44 patients in this group.

ABSTRACT

We present a case report to illustrate the differential diagnosis and management of a multiple plexiform schwannoma involving the main nerve trunks of the upper limb in a 4 year-old boy. The tumour was diagnosed by MRI scan and histological examination. A 12 year follow-up is presented in which, despite multiple recurrences, the condition has been controlled by surgical means and the limb salvaged.

ABSTRACT

INTRODUCTION: Objective assessment of hand injuries is a complex subject. However, an objective assessment, leading to a score, can help in predicting outcome and can be used as a research tool. Campbell and Kay have devised one such score known as "hand injury severity score" or HISS [J. Hand. Surg. [Br.] 21 (3) (1996) 295]. A study on this score has been carried out in our institute. The idea was to see if the hand injury severity score, correlates with the functional outcome as measured by disability arm shoulder and hand score (DASH), after a period of minimum 2 years. METHOD: All the hand injury patients admitted in the hospital were assessed at the time of admission, and objective information was documented on a hand injury documentation form. The form captured all the data required to calculate "hand injury severity score" . A sample of 70 patients admitted during the first 6 months of 1999 was taken and their scores were calculated. The sample was selected such, that it had a reasonable representation of hand injuries of all severities. After obtaining a due approval from ethics committee, all these 70 patients were sent a DASH questionnaire. A total of 23 patients replied. Spearman's rank correlation test was used to analyse the correlation between the severity of hand injury as assessed using HISS, and functional outcome as measured using DASH. Correlations between the outcome and skeletal component score, outcome and motor component scores, and outcome and Integument component scores, were assessed separately. RESULTS: The study shows a statistically significant association ( r = 0.7182, P = 0.000165) between the severities of injury and the functional outcome. The functional outcome also shows a statistically significant association with the severity of injury to skeletal component (r = 0.5151, P = 0.014083) and motor component (r = 0.6797, P = 0.000507). However, the severity of injury to integument component, as measured by HISS, does not show any association with the outcome (r = 0.3571, P = 0.102736). This study supports the overall structure of the HISS. However an improvement in the integument component scoring is required to improve overall accuracy.

ABSTRACT

Distal tibial physeal fractures are the second most common growth plate injury and the most common cause of growth arrest and deformity. This study assesses the accuracy of pre-operative planning for placement of the screws in these fractures using either standard radiographs or CT scans. We studied 62 consecutive physeal fractures over a period of four years. An outline of a single cut of the CT scan was used for each patient. An ideal position for the screw was determined as being perpendicular to and at the midpoint of the fracture. The difference in entry point and direction of the screw between the ideal and the observers' assessments were compared using the paired Student's t-test. There was a statistically significant improvement (p < 0.0001) in the accuracy of the point of insertion and the direction of the screw on the pre-operative plan when CT scans were used rather than plain radiographs. We would, therefore, recommend that CT scans are routinely used in the pre-operative assessment and treatment of distal tibial physeal fractures.

ABSTRACT

Complex fractures are generally assumed by our profession to require adequate training and continuing practice to treat optimally. The quantity of complex fractures treated in individual hospitals and by or under the care of individual orthopaedic consultants may have implications regarding the quality of care for particular patients and also for the training of specialist registrars.A complex fracture was defined as a comminuted peri- or intra-articular fracture or segmental shaft fracture: fractures acknowledged at specialist fracture courses and by special trauma surgeons to require particular training and experience to treat optimally. The AO classification was used: most fractures were in AO groups B and C [M.E. Muller, S. Narazian, P. Koch, J. Schatzker, The Comprehensive Classification of Longbones, Springer, Berlin, 1990]. Theatre records were used to identify all operated orthopaedic trauma cases over a period of 1 year in one District General Hospital (DGH) and one University Hospital, each serving populations of over 300000 and for 6 months in one DGH (population approximately 300000). Radiographs and hospital records were reviewed by two orthopaedic surgeons and the number and type of complex fractures documented as defined above. In hospital A, 69 complex fracture operations were carried out under the care of six consultants in 12 months. In hospital B, 24 complex fractures were treated by five consultants over a 6-month period and in hospital C, 127 complex fractures were treated by 10 consultants over a 12-month period. Some consultants (different consultants for different fracture regions) did not operate on any complex fracture of the proximal, mid, or distal humerus; proximal, mid, or distal radius or ulna; proximal, mid, or distal femur; proximal, mid, or distal tibia; calcaneum; peri-prosthetic; Lisfranc; or talus fracture during the specific time period. Some consultants only treated one or two such fractures. Where two surgeons had developed an area of special interest and cross-referral were encouraged individual surgeons were operating on up to 25 complex cases in their area of interest.This audit has shown that individual complex fractures present infrequently to particular hospitals and surgeons. This finding raises questions about the optimal management of such fractures: are we maintaining a sufficient level of expertise, or should there be more cross-referrals to surgeons with a specific interest either in trauma or in a particular anatomical region?

ABSTRACT

1. In vitro studies with the selective dopamine D3 receptor antagonist SB-277011 were conducted in liver microsomes and homogenates from rat, dog, cynomolgus monkey and human to correlate the rate of metabolism with the in vivo pharmacokinetics of the compound in rat, dog and cynomolgus monkey. 2. In the presence of NADPH, SB-277011 was relatively stable in the presence of liver microsomes from rat, dog, cynomolgus monkey and human with an intrinsic clearance (CLi) of < 2 ml min(-1) g(-1) liver for all species. In total liver homogenates, SB-277011 was metabolized at a similar rate in rat and dog (CLi < 2 ml min(-1) g(-1) liver) to that in liver microsomes but in cynomolgus monkey and human (CLi = 9.9 and 45 ml min(-1) g(-1) liver, respectively) the intrinsic clearance was approximately 6- and 35-fold higher, respectively, than that in liver microsomes. 3. In the absence of NADPH, SR-277011 was rapidly cleared in liver homogenates from cynomolgus monkey and human (CLi = 7.4 and 27 ml min(-1) g(-1) liver, respectively) demonstrating that a significant pathway of metabolism of this compound was via an NADPH-independent non-microsomal oxidative route. This pathway was sensitive to inhibition with isovanillin suggesting that the enzyme responsible was aldehyde oxidase. 4. The in vivo pharmacokinetics showed that the plasma clearance of SB-277011 was low in rat (20 ml min(-1) kg(-1)), moderate in dog (14 ml min(-1) kg(-1)) and high in cynomolgus monkey (58 ml min(-1)kg(-1)), which is consistent with the in vitro findings and demonstrated a greater capacity for the monkey to metabolize this compound. The oral bioavailability of SB-277011 in rat, dog and cynomolgus monkey was 35, 43 and 2%, respectively. Given the high clearance of this compound in cynomolgus monkey, the low oral bioavailability is probably as a result of high first-pass elimination, specifically by aldehyde oxidase, rather than poor absorption. 5. The high in vitro clearance of SB-277011 in human liver homogenates and the involvement of aldehyde oxidase in the metabolism of SB-277011 indicates that the bioavailability of the compound is likely to be low in human.

ABSTRACT

The hypothalamic peptide orexin-A and the orexin-1 receptor are localized in areas of the brain and spinal cord associated with nociceptive processing. In the present study, localization was confirmed in the spinal cord and demonstrated in the dorsal root ganglion for both orexin-A and the orexin-1 receptor. The link with nociception was extended when orexin-A was shown to be analgesic when given i.v. but not s.c. in mouse and rat models of nociception and hyperalgesia. The efficacy of orexin-A was similar to that of morphine in the 50 degrees C hotplate test and the carrageenan-induced thermal hyperalgesia test. However, involvement of the opiate system in these effects was ruled out as they were blocked by the orexin-1 receptor antagonist SB-334867 but not naloxone. Orexin-1 receptor antagonists had no effect in acute nociceptive tests but under particular inflammatory conditions were pro-hyperalgesic, suggesting a tonic inhibitory orexin drive in these circumstances. These data demonstrate that the orexinergic system has a potential role in the modulation of nociceptive transmission.

ABSTRACT

The term dual diagnosis is frequently used by mental health professionals to refer to people who have mental illness complicated by substance abuse. A less commonly recognized population are those individuals who have the dual diagnosis of mental retardation and mental illness. In this paper the author discusses (1) the mental health needs of persons with mental retardation and (2) the current state of services for them. There is a significant lack of appropriately trained professionals to help address the needs of this population. Traditionally, nurses have primarily been identified as providers of physical care. Advanced practice psychiatric nurses, however, are an underutilized group of professionals who have the capacity to assume a leadership role in clinical care, service coordination, and advocacy for individuals and families affected by mental illness and mental retardation.

ABSTRACT

Brookfield's (1995) four critically reflective lenses are adapted from teaching and applied to nursing within this article. The lenses are used as a framework for exploring the author's feelings associated with diagnosing a life-threatening problem in intensive care in the presence of a disagreeing doctor. The issues surrounding the distinctions between medicine and nursing are explored. Wellington and Austin's (1996) five orientations to reflection provide the framework for the author's 'metacognition'--his thoughts about his thoughts. These are communicated by way of a critical commentary.
